John R Boyle - said to be murdered in Montana

Looking for obit, newspaper article, any proof that John R Boyle, born 1872 Vermont was murdered (stabbed to death) in Montana. He either owned or worked in a roadhouse at the time of his death. It would have been after 1900...family story says two of his brothers traveled from New Hampshire to Montana to bring his body home. I realize this is a long shot but any help appreciated.
